1. Introduction

The directions below will produce the RedHat (currently version 6.2 is used, 7.0 is in development) Linux

system that boots into the bare (=no window manager, like gnome, kde or fvwm2) X server and starts

Netscape Navigator (not Communicator, which includes Main and News clients). Upon exiting the browser

the X server is restarted and the new Netscape process is launched as needed. The system is intended for

Internet Kiosks and similar applications. Security is emphasized at all the stages of the setup.

This HOWTO will be updated (maybe significantly) as long as more reports about the deployment of such

boxes will arrive.

abstract finished

1.5 TODO

Write abstract

Suggested hardware

· .Xdefaults disable some keys (Alt−Ctrl−F1)

X server port 6000 attacks, do something about them

X server under root, bad

Eliminate more unneeded RPMs

Implement /etc/pam.d/limits.conf to prevent netscape bloat and system crash (well, by causing it to

crash before bloat ;−) ), see Security HOWTO

Protect some files with chattr is nice

Provided CDROM booting considerations

Redo everything for RedHat 7.0

2. OLD GUIDE: The Linux Public Web Browser

mini−HOWTO by Donald B. Marti Jr., dmarti@best.com

v0.3, 5 January 1998

The basic idea here is to give web access to people who wander by, while limiting their ability to mess

anything up.
